Weight loss program aims to cut cancer risk in BRCA and lynch syndrome carriers
NCT ID NCT04125914
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a weight management and health behavior program for people with BRCA or Lynch syndrome mutations, who have a higher risk of certain cancers. Participants receive diet tracking, exercise guidance, phone coaching, and online support to help them lose weight and adopt healthier habits. The goal is to see if these lifestyle changes can lower cancer risk in this high-risk group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- behavioral intervention (diet, exercise, coaching, text messages, Facebook group)
- What this could lead to
- If successful, this program could help people with hereditary cancer mutations lower their cancer risk through lifestyle changes.
- What could go wrong
- This is an early-stage behavioral study, not a drug trial. Results depend on participants sticking with the program, and it may not work for everyone.
